EDWIN G. MUMMERY, OF DETROIT, MICHIGAN.

To all whom it may concern:

Be it known that I, EDWN MUMMERY, a citizen of the United States, and aresident of Detroit, in the county of iiyne and State of Michigan, haveinvented a new and Improved 'Iydrocarbon- Burner,y of which thefollowing is a s ecicution.

My invention re ates to means' for properly mixing steam vsind thevapors of hydrocarbon liquids so as to form a vapor capable of givingofi' greet heat when burning', andits object is to so improve over theconstructions of the prior art. that the hydrocarbon burner thusproduced will be more efficient with practically no increased cost ofconstruction.

My invention lconsists in so lforming the burner-piin or tray of thisconstruction that the burning hydrocarbon liquid at the starting of theoperation of the burner will 4be located where it will be mostefficient; sind in so constructing the steqnngencratiug chamber that thefiaincs of the burning hydrocarbon, and afterward, of the mixehydrocarbon vapor and steam Vwill not on the saine with most desirableheatingr efiect.

In the accon'ipanying drz'iwing, Fi iure 1 is a side elevation ofthisimproved construction, the burner-pen being partially broken away toshow themeinburner-pipe. Fig. 2 is a plein of the same from the line 2-2of Fig. l. Fig. 3 is an end viewv of the burner, from the right in Fig.1, the end of the burner-pan 'being broken ewiiy. Fig. 4 is u persective oit thesteamgenerator and one o the superheaters tor the .Similarreference characters refer to like parte throughout the several views..I

' The various parts of the. construction shown, with the exceptiono thesteem-gen erator und the burner-pan, may be similar. in general designto those already known.- The steam-generating-chember 1 connecte to thelfirst superheater 2 'by ineens of the pipe 3. The superheeter 2connects to the 'second superheeter 4 by the pipe. 5, while the secondsuperheater connects to the third super.- heater 6 by means of the pipe,7. It will beV noticed that in this construction, the steam must travelthe entire length of the superheaters in succession. A pipe '8 connectsthe third su erheater with the upper"or intake-end o the mixing-chamber9 into which also connects the hydrocarbon feedpipe 10.

proper supply-tank.

an' Y 'ilvhe lower end of the mixin -chainber 9' connects to theburner-pipe 12 y means of the pipe 13. A pan 14 extends up aroundrAmixes with the hydrocarbon, forming e. gas,

which burns freely with o. dame of intense flow of` fuel to thismixinglchainber from;4

As the steam passes throng' o heat. 'Before the steam is generated, the`liquid hydrocarbon flows down the mixing; chamber, through the pipe 13and out ofE the small aperture 28 in the bottom ofthe ipe 12, andrunsdown to tlielour-V i est portion of the lbottom 15 of the pan 14;' 29orl in the trough formed burner wherejit may be li hted. W'ickingasbestos may be lai by the bottom and side to assist inthe inik r y tialoperation of the burner.

To effect quicker heelting of the water in the steun-generator, quickerproduction of the perfect gas, the generator is provided with 'ii seriesof holend thereby the low projections18 in .the forni of water closedouter ends, which extend inward over the iame of the liquid hydrocarbonburning in-the trough from the asbestos 29, and are preferably et rightanglee to the sidof the generator in 'paralle staggered rows. r

1n order to secure thel most desirable heating eifect from the burningof the liquid,the combustion should occur next adacent the side of thesteam-generator, and the bottoni of the burner-pan is eccordin lyinclinedv tubes, havin? es shown The burner-pan isl ormed with .1"

e series of holes 17, preferably in both sides,

to admit air to the burning liquid or :gasp

e water. indicator v20 formed with angupwardly-openin chamba." 21,kwithin which I -generatdr undhave`V v ter-trink is a waterfeed pipe 19in which is is e partition 2 projectingupward to the required height ofthe water-line in the steam-generating chamber 1.v yThe checkvalve 2Bmay be located in the water-supply pipe to prevent back-pressure ofsteam, the

- check-valve however, being so constructed as to-perm'it the water topass freely to the generatorn i Connected with the pipe 19 is a shallowwater-basin 24 which may be located at any desirable place, and is ofsufiicent height tc cont-ain water standing just above the partition 22.Supports 25 extend upward to receive the adjusting screws 26 whichsupportl the tank 27. A cap 30 gives admittance to he tank, while a pipe3l leads to the basin 24, the flow of Water being controlled by thevalve 32.

The burner is adapted for furnaces, ranges and stoves and itsproportions and details may be varied so it will be adapted for theparticular location where it is to be ein- 4 ployed.

Haring now explained my construction, what claim as my invention anddesire to .secure vby Letters Patent is etages the ed e of one side ofthe pan next to the low si e or" the bottom and having hollow tubesextending inwardly, toward the space over the burner-pipe.
